Android listview json array

If your application stores data locally and you are planning to transfer data across different platforms (e.g. between mobile apps and websites, it is a good idea to store the data in JSON format. In this Android tip, I am going to show you how to read JSON array from the assets directory to display in a ListView.
Now in the assets directory of your current working project, you create a JSON file called jsondata.json. In the file, you have JSON data as shown below. There is a JSON array. In the JSON array, there are three JSON objects. Each object contains information (id, name, and sex) of a student. So, there are three students in the JSON file that will be displayed in the ListView.

In the MainActivity class, you write code as shown below to read data from the JSON file in the assets directory, convert it to ArrayList, and bind the ArrayList to a ListAdapter object. Then pass the ListAdapter object to the setAdapter() method of the ListView.
